[0013] Beneficial effects

[0014] The utility model provides a coating machine anti-film scratch rotating shaft frame. Compared with the existing technology, it has the following advantages:

[0015] 1. The coating machine's anti-film scratch shaft frame can move the rotating rod through the movement of the rotating shaft. Since the rotating rod passes through the transverse groove, the rotating rod moves along the transverse groove. The rotating rod is located at different positions in the transverse groove. The movement of the rotating shaft can prevent the film from being in a taut state, which is convenient for subsequent operations. After that, the movement of the rotating shaft exposes the cross bar, allowing the fan to move at the same time. The fan blows the film above, causing the film to produce an upward arc state, which is at a certain distance from the rotating shaft. This can reduce the contact between the rotating shaft and the film and prevent scratches.

[0016] 2. The coating machine prevents the film from scratching the shaft frame. The length of the rubber pad is equal to the sum of the lengths of multiple mounting holes. In this way, no matter which mounting hole the screw is combined with, it will contact the screw. The lifting plate and the rubber pad can block the screw to prevent it from moving or falling, which is convenient for long-term stability of the shaft. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-3 The utility model provides a technical solution: a coating machine anti-film scratch rotating shaft frame, including a bracket 1, a moving mechanism 2 is provided on the top of the bracket 1, a rotating shaft 3 is provided on one side of the moving mechanism 2, a base 4 is provided at the bottom end of the bracket 1, a lifting plate 5 is provided above the base 4, and a rubber pad 6 is provided on the surface of the lifting plate 5 close to the bracket 1.

[0024] The motion mechanism 2 includes a rotating plate 201, which is fixedly connected to the rotating shaft 3. A groove 202 is provided on the surface of the rotating plate 201 on one side close to the bracket 1, and a transverse groove 203 is provided on the top surface of the bracket 1. A round rod 204 is provided inside one end of the groove 202, and the round rod 204 is movably connected to the groove 202. A connecting rod 205 is provided at one end of the round rod 204, and a fixed plate 206 is fixedly provided at one end of the connecting rod 205. A fan 207 is provided on the top of the fixed plate 206, and the number of fans 207 is multiple. A mounting hole 208 is provided at the bottom of the transverse groove 203, and the number of mounting holes 208 is multiple, and the multiple mounting holes 208 are arranged horizontally in a collinear manner. An adjustment plate 209 is provided at the top of the bracket 1.

[0025] A rotating rod 210 is fixedly provided on one side of the rotating plate 201 . The rotating rod 210 passes through the transverse groove 203 , and the rotating rod 210 contacts the bracket 1 .

[0026] A motor 211 is provided at one end of the rotating rod 210 . The bottom of the motor 211 is fixedly connected to the adjustment plate 209 via a support rod. A ring 212 is fixedly provided at the top of the adjustment plate 209 , and the round rod 204 passes through the ring 212 .

[0027] A sliding rod 213 is provided at the bottom of the lifting plate 5, and the bottom end of the sliding rod 213 is movably connected to the bracket 1. A connecting spring 214 is provided at the bottom of the sliding rod 213. A cross bar 215 is provided at one end of the connecting rod 205. One end of the cross bar 215 extends to the interior of the bracket 1, and the other end of the cross bar 215 is fixedly connected to the connecting rod 205.

[0028] See also Figure 1 and 4 A screw is provided on one side of the bottom end of the adjustment plate 209 , and the screw is located between the rubber pad 6 and the adjustment plate 209 .

[0029] When working, place the whole near the coating machine, move the lifting plate 5 downward as needed, and push the sliding rod 213 downward. Since the sliding rod 213 is movably connected to the bracket 1, the sliding rod 213 is separated from the screw through the downward movement of the sliding rod 213, and the connecting spring 214 under the lifting plate 5 is squeezed, causing the connecting spring 214 to deform, which is convenient for subsequent operations. Then, the adjusting plate 209 is moved, because the rotating rod 210 passes through the ring 212 fixedly connected to the adjusting plate 209, causing the ring 212 to move together. The rotating plate 201 and the rotating shaft 3 are rotated at the same time by the horizontal movement of the rotating rod 210, so that the distance between the rotating shaft 3 and the film is reduced to prevent the film from being in a tight state during winding, which is convenient for subsequent operations. After the adjustment plate 209 is moved, the screw is connected to the adjustment plate 209, so that the screw moves at the same time and is aligned with one of the mounting holes 208. After alignment, the screw is rotated to allow the screw to enter a mounting hole 208 and merge with the bracket 1. By combining the screw and the mounting hole 208, the rotating plate 201 and the rotating shaft 3 are prevented from moving, thereby improving stability. After that, the lifting plate 5 is loosened, and the lifting plate 5 is automatically moved upward by the connecting spring 214, so that the lifting plate 5 gradually moves to one side of the screw and contacts the screw, so that the rubber pad 6 fixedly connected to the lifting plate 5 contacts the screw. The lifting plate 5 and the rubber pad 6 can block the screw to prevent the screw from moving or falling, thereby facilitating the long-term stability of the rotating shaft 3. Moreover, the groove 202 can be opened by the movement of the rotating plate 201. The round rod 204 inside moves and pushes the movement of the connecting rod 205 and the fixed plate 206. Since one end of the cross bar 215 extends to the inside of the bracket 1 and the other end of the cross bar 215 is fixedly connected to the connecting rod 205, the cross bar 215 is exposed. When the fixed plate 206 moves, the fan 207 above moves at the same time. The fan 207 is subsequently used to blow the film above, causing the film to produce an upward arc state, which is at a certain distance from the rotating shaft 3. This can reduce the contact between the rotating shaft 3 and the film and prevent scratches.
